Revisiting Chris Davis’ Troubling Trend
Few players can heat up the way Chris Davis can. Baltimore’s left-handed slugger has homered five times in his last six games, and over the last two weeks has ran a .432 ISO and 183 wRC+. It’s a sufficient number of stretches like this one over the course of a season that leave Davis winding up among the league’s best hitters, as he did in 2013 and 2015.
Few players can get lost the way Davis sometimes can too, though, and certainly few are getting paid more. Before Davis’ current two-week hot stretch began, the $161-million man was barely a league-average hitter, posting a 103 wRC+ over his first 451 plate appearances in the first year of the seven-year contract he signed in the offseason. Even when Davis has struggled to make contact, he’s walked enough to maintain a respectable on-base percentage, and he moves well enough for a slugger to accrue base-running value and avoid being a liability in the field. So, the season as a whole hasn’t been a disaster: he’s projected to finish the year with roughly 3.5 WAR. But the bat’s what earns Davis his money, and when Dan Duquette handed out the largest free-agent contract in franchise history this January, he certainly wasn’t hoping to see it look like this so soon.
And just before Duquette handed out that very contract, our own Jeff Sullivan, writing for FOX Sports, pointed out a troubling trend within Davis’ game, regarding that very bat. Sullivan noted that Davis was on a five-year run of increasing his pull rate, pulling air balls more each year, and pulling ground balls more each year. The culmination of that five-year increase was Davis, last year, ranking in the 99th percentile in pull rate. In other words, he’d become the most pull-happy hitter in baseball. The extra pulled grounders resulted in more shifts, and more outs. The extra pulled air balls presented a potentially worrisome indicator, too. To quote directly from that article:
People say that, as hitters age, they try to become more pull-happy, to squeeze out as much power as possible. That’s not the only explanation, but this could be Davis adopting and embracing an old-player skill. Which isn’t what you want to think about a player who’s been offered a seven-year contract.
